Vermont gets less sunlight than almost any other state — but it also has some of the highest electricity rates in the country. Here's the real story:
Vermont's average electricity rate is $0.204/kWh (EIA, 2025), which is about 39% higher than the national average. For a household using 500 kWh/month, that's a monthly bill of ~$102. Solar can eliminate most of that — and with net metering, excess summer production covers winter usage.
Green Mountain Power (GMP), Vermont's largest utility, offers a unique "solar + battery" program that allows customers to lease a home battery (Tesla Powerwall or similar) as part of their solar installation. GMP can draw from your battery during peak demand events, and you receive bill credits. This program has made solar + storage more accessible in VT.
Vermont's net metering policy allows solar owners to receive full retail rate credit for excess electricity sent to the grid. There's no cap on system size for net metering (up to 100% of your annual usage), making it one of the more favorable policies in New England.
The 30% Federal Investment Tax Credit (ITC) applies to Vermont solar installations through 2032. For a $35,000 system (before incentives), that's $10,500 back as a tax credit.
Vermont's winter snow doesn't prevent solar from working. The reality:
GMP offers several solar-friendly programs:
30% of total system cost (through 2032). Applies to equipment, installation, and permitting fees. The credit is non-refundable but can be carried forward to future tax years.
System size: 6 kW (18 × 350W panels)
Roof direction: South-facing, 38° tilt
Electricity rate: $0.204/kWh (GMP)
Annual production: ~6,800 kWh (NREL PVWatts estimate for Burlington, VT)
| Item | Amount |
|---|---|
| Annual solar production | 6,800 kWh |
| Value at retail rate ($0.204/kWh) | $1,387 |
| Minus estimated degradation (Year 1 = 100%) | -$34 (0.5%/year) |
| Net annual savings (Year 1) | $1,353 |
Monthly savings: ~$113 | Yearly: $1,353
With electricity inflation at 4%/year and panel degradation at 0.5%/year:
Note: These are estimates. Actual savings depend on your specific electricity usage, roof orientation, shading, and future electricity rate changes.
Yes — and better than you might think. Here's the data:
| Month | Production (kWh) | % of June Production |
|---|---|---|
| January | 320 | 21% |
| February | 450 | 30% |
| March | 720 | 48% |
| June | 1,480 | 100% |
| December | 290 | 20% |
Key takeaway: While winter production is lower, Vermont's long summer days (up to 15.5 hours of daylight in June) more than compensate. A properly sized system can still achieve net-zero annual electricity bills.
Installing solar in Vermont typically takes 4–8 weeks from contract signing to system activation. Here's the typical process:
A solar installer visits your home to assess roof condition, orientation, shading, and electrical panel capacity. They design a system sized to your electricity usage and roof space.
The installer handles city/county building permits and utility interconnection agreements. Vermont has relatively straightforward permitting compared to some states.
Actual installation typically takes 1–3 days for a typical residential system. The installer mounts panels, installs inverter and racking, and connects to your electrical panel.
After installation, a city/county inspector verifies the system meets code. Then your utility installs a net meter and grants permission to operate (PTO).
Yes. Green Mountain Power and other Vermont utilities offer net metering. You receive full retail rate credit for excess electricity sent to the grid, which can be used to offset electricity consumed at night or during winter months.
A typical 6 kW solar system in Vermont saves about $113/month, or $1,353/year. Over 25 years, total savings exceed $61,250 (assuming 4% electricity inflation and 0.5% annual panel degradation). Your actual savings depend on your electricity usage, roof direction, and local rate.
South-facing roofs capture the most annual sunlight in Vermont. Southeast/southwest-facing roofs capture about 92-95% of south-facing production. East/west-facing roofs capture about 80-85%. North-facing roofs are not recommended for solar in Vermont due to low winter sun angles.
Not necessarily. With net metering, you can use the grid as a "virtual battery" — sending excess summer production to the grid and drawing it back in winter. However, battery storage is valuable if you want backup power during outages (which can happen in Vermont ice storms). Green Mountain Power's solar + battery lease program is worth exploring.
Vermont's net metering policy is among the most favorable in New England. Massachusetts (SMART program) and New Jersey (TREC) have different incentive structures, but Vermont's combination of high electricity rates and full retail net metering makes solar economically attractive despite lower sun hours.

The average cost of a residential solar system in Vermont is $15,000-$25,000 before incentives (for a 6-10 kW system). After the 30% federal Investment Tax Credit (ITC), the net cost drops to roughly $10,500-$17,500. Actual costs vary based on roof complexity, panel brand, installer choice, and local permitting fees. Vermont homeowners should get at least 3 quotes to compare pricing.
All U.S. homeowners qualify for the 30% federal Investment Tax Credit (ITC) through 2032. This credit reduces your federal taxes by 30% of your total system cost. In addition to the federal ITC, some states offer additional rebates, property tax exemptions, or sales tax exemptions on solar equipment. Check with your local utility and the Database of State Incentives for Renewables & Efficiency (DSIRE) for Vermont-specific programs.
The typical solar payback period in Vermont ranges from 7 to 12 years, depending on your electricity rate, system size, available incentives, and financing terms. After the payback period, your solar panels essentially produce free electricity for the remaining 15+ years of their 25-30 year lifespan. Higher electricity rates and strong sun exposure lead to faster payback periods.
Yes. According to a study by Lawrence Berkeley National Laboratory (LBNL), homes with solar systems sell for an average of $15,000-$25,000 more than comparable homes without solar. The exact premium depends on your location, system size, and age. Many states including Vermont offer property tax exemptions for the added value from solar, so you won't pay higher taxes even though your home is worth more.
Solar works best on south-facing roofs with minimal shading, but east-west orientations can still produce 80-90% of optimal output. Key factors include: roof condition (should have 15+ years of life left), tilt angle (30-45 degrees ideal), and shading from trees or nearby buildings. A reputable installer will perform a free site assessment using satellite imagery to estimate your production potential before you commit to anything.
